LOOK FOR FIRE-ARMS.

SPECIFICATION forming part of Letters Patent No. 313,170, dated March 3,1885.

(No model.)

To aZZ whom it may concern.-

Be it known that 1, JACOB BREDA BULL, a subject of the King of Norway,and residing in the town of Ohristiania, Norway, have in- 5 ventedcertain new and useful Improvements in Gun-Locks; and I do herebydeclare the following to beafull, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

My invention relates to an improvement in fastenings for gun-locks.

In using most of the present construction of gun-locks the huntsmancannot as a rule 1 go into the field with his gun cooked, on account ofthe danger of unintentionally letting off the gun. Thepresent inventionis designed to make this possible without any danger. tained' of hai ingthe gun alwaysready to fire, and hence the animals cannot escape soeasily. Said object is obtained by arranging a hook or other shaped stopin the lock in contact with the trigger in such way that it isimpossible to fire in the usual way. Such an arrangement is, in ageneral way, not new; but the constructions hitherto used suffer fromthe disadvantage that the disengaging of said hook (as must take placebefore firing) is just as troublesome and takes up as much time asraising the cock, for which reason the advantage is illusory. To obviatethis difficulty, the disengaging-trigger for the hook or stop is appliedin the present invention on top of the butt of the gun, so that in theposition of the right hand which it must assume in firing the hook orstop trigger can easily or comfortably be found by the thumb. Thedisengaging is done by a pressure of the thumb on said trigger at thesame moment that the gun is placed in positionthat is, ready to fire.

In the accompanying drawings, Figure 1 is a view in side elevation ofthe lock-section of an ordinary Lefaucheux double-barreled shotgun withlock plates and locks removed showing the application of my improvementthereto. Figs. 2, 3, 4, and 5am modifications.

5o Zrepresents the rear end of the barrels; Z

In this way the advantage is oband l the upper and lowerfastening-rails, respectively.

S is the rod that holds the cock in position, and 01 represents thetriggers. Ahook or an gle lever, a, pivoted on the pin b, is held inengagement with the trigger by the spring 0. The hook or angle lever isdisengaged from the trigger by means of the spring-bar 6, provided witha tooth or projection, e, and operated by a thumb-button, e, secured tothe 60 bare, and having a free sliding motion in a perforation in therail Z. It will be readily seen that a pressure on the button 0 causesthe hook or angle lever to rotate to the left and disengage the trigger,and that the releasing of the pressure on thesaid button will leave thespring 0 free to return the lever into position in engagement with thetrigger.

The modification represented in Fig. 2 consists in attaching thespring-bar 6 directly to the end of the angle-lever a, whereby the saidspring 6 performs the functions of both springs e and c in Fig. 1.

Fig. 3 represents the'thumb-button, connected directly with the end ofthe lever a, and .7 5 the spring 0 performs the functions of bothsprings e and c in Fig. 1.

In Fig. 4 the modification consists in attaching the button directly tothe lever, and the spring 6 performs the functions of the springs e andc in Fig. 1.

Fig. 5 represents a modification quite similar to that shown in Fig. 3,with the exception of the recess formed in the fastening-rail, in whichthe'thumb-button is received, its up per surface resting flush with thestock.

It is evident that many modifications other than those shown may beresorted to without departing from the spirit and scope of my invention,particularly in adapting my invention to guns of different make thanthat shown; hence I do not wish to limit myself, strictly, to theconstruction .hereinset forth; but,

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. In a gun, the combination, with a stock and trigger, of aspring-actuated angle-lever pivoted Within the stock and adapted when inanorinal position to overlap and rest on the trigger, and avertically-movable button for moving the end of the angle-lever off oraway from the trigger.

2. In a gun, the combination, with a stock and trigger, of aspring-pressed hook or angle lever pivoted within the gun-stock andadapted to engage the trigger and lock it against action, a spring-barprovided at its free end -10 with a projection adapted to engage theupper end of the angle-lever, and a button engaging said springbar,substantially as set forth. I

In testimony whereof I have signed this specification in the presence oftwo subscribi5 ing Witnesses.

JACOB BREDA BULL.
